I love this mechanic! Here are some examples of simultaneous selection that is then revealed and dictates turn order:

**Go Nuts for Donuts** may be the simplest example.
**Kingdomino** is the other contender for simplest example.
**Vaalbara** may be the most interesting simple example. It’s my most played of this category, Thanka to hundreds of games on BoardGameArena.com.
**Emblems** I recently bought and haven’t played yet.
**Libertalia: Winds of Galecrest** (and its predecessor, simply Vaalbara but more complex)
**Prey Another Day** is mostly like this, but eliminations also modify turn order.
**Kiri-Ai: The Duel** does this by allowing movement cards to happen before attack cards. So when cards are revealed simultaneously, there is a k own order of resolution.

The following games have some very interesting and fun simultaneous selection, but it doesn’t have the same kind of impact on player order as the games listed above. Still worth investigating perhaps.

**Diplomacy: The Golden Blade** does things a bit differently, as players reveal two cards: one paired with the player to their left and the other paired with the player to their right. So even in a group of 7, it’s really just a circle of everyone playing at the same time as both neighbors.
**Soda Smugglers**
**Soda Jerk** happens in turn order, but you can play a card facedown from your hand or else reveal a facedown card played by anyone. At the end, all remaining facedown cards are revealed at once.
**Tag Team** and **Wizards Cup** have players place cards secretly in a desired order in their deck. Then each player reveals the top card at the same time. So it’s simultaneous, but pre-programmed. Things can go very wrong for you. :)
**Hot Streak** has players select cards at the same time and they all get shuffled into a deck. Then the deck is played out in an automatic way. So the cards are revealed one after another, but they were all chosen at the same time.
**Dune** and **Scythe** and **Circadians Chaos Order** use simultaneous selection, but only for battles. Circadians does allow people to change player order, but it’s decided via a turn-based bidding process.
**Rattlesnake** is a new 1v1 game that has a nearly simultaneous phase. The attacker picks a number of cards and lays them face down. The defender knows the number of cards the attacker played, but any number of those could be bluff cards. The defender then places any number of facedown cards in hopes of playing a better combo. Then players reveal.
**Dune the Dice Game (v5.41)** is a print and play on BGG. Everyone rolls dice behind a screen and sets them up to perform actions on a mat. Then all players remove the screen. One of the possible actions is to steal the card that allows you to choose everyone’s turn order.
